Oz, I take on board your points and feel that perhaps we are talking around the same concept if but perhaps using different language. I agree that all control rests with the Dom, or in my case with my Domma, she controls every aspect of our relationship and me.
What I was referring to with regard to the balance of power remaining equal was in relation to the fact as you rightly state that although the Dom(me) is in total control the ability to cease play or even end the relationship is unaffected, both are equally able to do this. A form of MAD (mutually assured destruction) so to speak, both relying upon the other to continue, hence the need to work together and be open and honest.
My post stated that the whilst the balance remained unaltered, as above both being equally responsible for the ongoing success of the relationship the ratio or balance of that power is altered, as the dominant has total control, at no point did I try to state or do I feel that the level of power between my Domma and I is equal, to think such a thing would be detrimental to our relationship, and result in me suffering yet further, all be it deserved punishment. She maintains total control and holds all power, in submitting I have entrusted my power to her, totally.
Thanks for seeking to clarify the post though Oz, I do feel we are in agreement, and hope that having read my reply my Domma agrees !
